They are good points, but beyond me I'm afraid.
Personally USB and LDAP were important to me and they are just about ready for verification
What else matters, the other sme8 bugs don't seem like show stoppers to me, if it is to you make it known
Windows 7 and samba seem important, for the life of me I can't work out what's been fixed, whats to do and what feature requests eg Active Directory are appropriate for working on now, All this will go into sme8 not 7
